| b. 溫度分佈均勻。 | |
| c. 開門後溫度回昇速率。 | |
| d. 試驗槽內(nèi)之風(fēng)速及換氣率。 | |
| e. 試驗槽內(nèi)之隔熱密封。 | |
| f. 特殊換氣率調(diào)整裝置。 | |
| g. 依據(jù)測試標(biāo)準(zhǔn): | |
| JIS K-7217, K-7623, K-6301, ASTM D-2436, D-573, UL-746B, IEC-540, BS-6746, 903, ISO/DIS 4577 | |
| 換氣率測定方法 | |
| This method measures the air change rate of the std type oven as follows | |
| N=3590 (X-Y)x2 / VxDx | |
| |
| N: number of changes of air per hour | |
| X: Power consumption during air change (W) | |
| Y: Power consumption during no air change (W) | |
| V: total volume of oven (cm3) | |
| D: Density of oven ambient air (g/cm3) | |
